For many, sleep is one of the most natural, effortless things in the world. For countless others however, a deep rejuvenating night of sleep seems almost impossible to obtain. It's for the latter, those who long to feel rested in the morning, that Dr. Jeffrey Thompson has created this program. DREAMY MUSIC FOR SLEEP features over an hour of languid synthesizer ambience (created by the Harmonix Ensemble) laced with inaudible pulses of sound frequencies in the delta range. When used either alone or in conjunction with deep breathing exercises, this clinically-proven program will help you relax and drift off to sleep with ease. Contains no spoken word or subliminal messages and works well with light headphones or stereo speakers.
